Preheat oven to 325F. Coat a 9 inch baking pan with cooking spray. Mix the cookie crumbs and melted butter and press evenly into the baking pan. In a large bowl, with a hand mixer beat the cream cheese and sugar until blended. Pour over the crumb crust. Bake for 45 to 55 minutes or until center is just set. Chill 4 hours or overnight. Cut into squares and drizzle with the fudge topping before serving. Makes 16.
